Materials or methods not allowed in organic farming include:
Artificial (synthetic) fertilizers to add nutrients to the soil
Sewage sludge as fertilizer
Most synthetic pesticides for pest control
Using radiation (irradiation) to preserve food or to get rid of disease or pests
Using genetic technology to change the genetic makeup (genetic engineering) of crops, which can improve disease or pest resistance, or to improve crop harvests
Antibiotics or growth hormones for farm animals (livestock)
Please read and see it is a actual regulated US government standard and to have it on your product you must follow certain by law guide lines.
